EDVIN G. HASTINGS, OF XEVADA, IOXVA.

MUSIC-LEAF TURNER.

SPECIFICATION forming part of Letters Patent No. 310,199, dated January6, 1885.

Application tiled December 17, 1883.

To all whom, it may concern:

Be it known that I, EDWIN G. HAs'rINos, of Nevada, in Story county, andState of Iowa, have invented a Husic-Leaf Turner, of which the followingis a specification.

.Iy object is to provide a practical mechanical device and attachmentfor organs and pianos to turn the leaves of a music-book by theloot-pressure of the operator, so that he will need no assistant to turnleaves, and will not be required to remove his hands from the keyboard,and have no interruptions and pauses in the performance of a piece ofmusic, such as are frequently occasioned by using the hands in turningleaves while playing.

My invention consists in the construction and combination of abook-rest, a spool having toothed sectors, arms having toothed sectors,adjustable leaf-clasping devices, a cord, and cord-direeting-pulleys,ashereinafter fully set forth.

Figure 1 of my accompanying drawings is a perspective view of mybook-rest and base for my operating mechanism. Fig. 2 is an enlargedperspective view of the spool and two arms, having toothed sectors, andan adj ustable leaf-clasping device attached to one of the arms. Fig. 3is a perspective view of an organ having my complete device attached.Fig. 4 is a transverse section.

Jointly considered, these figures clearly illustrate the construction,application, and operation of my device.

a is the basepiece of my book-rest, in the form of a straight strip ofwood.

I) is a board ofcorresponding length fixed on top of the piece a, toproject upward at any angle desired.

Z) are triangular-shaped pieces lixed in the angle formed by the twopieces a and I), for the purpose of uniting them securely and rigidly.

Z) is an opening formed in the bottom and center of the board Z).

2/ are brackets fixed to the front face of the board I), to support ahook.

c is a pin or post fixed in the base-piece a, to support the spoolhaving toothed sectors.

0 is a similar post, upon which series of arms having toothed sectorsare placed and operated.

d is a spool, that has a series of toothed see (X0 model.)

tors, 1 2 3, on its periphery at different points of elevation.

d is a eordpulley fixed to the top of the spool.

ff represent a series of arms having perfo rated toothed sectors f ontheir ends, adapting them to be pivoted to the book-rest by placing thesectors upon the post 0.

f are flanges on the lower sides of the sec tors f, to keep the armsseparated, and to extend under and between the toothed sectors on thespool (Z as it revolves.

g is a sliding loop secured to one of the arms f by means of aset-screw.

g are curved wires fixed to the loop to extend up ward to clasp theleat'of a m usic-book.

71. represents a washer placed upon the post a and top of the sectorsand arms ff.

h is a brace connecting the top ends ol the posts 0 and c.

i t are pin-whecls journaled to the pedal frame of an organ or piano, orto brackets eontiguous thereto. Pins projecting from their sides areadapted to be pressed by the operators feet, and thereby turned to windthe ends of a cord, 7:, upon pulleys Z, fixed to the axes of the wheels1.

l- 5 G 7 are pulleys, over which the cord k is directed from thepin-wheel t' to the pulley (7. on top of the spool (I. The bearings ofthese cord-directing pulleys are attached to the organ or piano in anysuitable way, so that the pulleys and cord will notinterl'ere with theoperative mechanism of the instrument.

In the practical operation of my invention thus constructed and applied,I simply place an open music-book upon the book-rest, turn all the armsto the left, and connect the leafclasping devices carried by the armswith the leaves that are to be successivelyturned. To turn a leaf fromleftto right at the proper mo ment, I simply press the pin-wheel on theright of my feet so that it will make a partial revolution, and in sodoing wind the end of the cord upon the pulley on the end of the axle ofthe erank-wheel, and thereby rotate the spool having toothed sectors.lhe upper most arm, having its toothed sect-or engaged with thecorresponding sector of the spool, will be swung from left to right bythe rotary motion and fractional revolution of the spool, and, by meansof the leat clasping device,

carry and turn the leaf from left to right. I tors, 1 2 3, and a pulley,d, a series of arms, Each leaf to be turned can thus be instantly f,having toothed sectors on their ends and moved by foot-pressure, whilethe fingers and carrying leaf-clasping devices, pin-wheels 13 z, 1 handsremain upon the key-board. To turn having pulleys Z, a cord, 1:, andeol'dmlireeting' back the leaves from right to left, reverse mo 1pulleys 4L 5 6 7 arranged and combined relzi tions are imparted tothearms successively by i live to each other, and an organ or piano, insimplypressing theleft cruuk-ivheelmul wind- I the manner sellorlih, forThe purposes speciiug the opposite end of the cord upon thepulfled. leyon its axle.
